Try looking at "alternate data streams":

Also consider "cluster tips"

Do you really know what all those chips on your MoBo do?...................is that really a capacitor? EEPROM chips?

In answer to your specific questions:

1. YES...................NTFS already does: see above link.
2. YES...................they already do with bad sector management?

Also hard drives contain a lot of "secret data" in that it is not user accessible.

If you don't believe me, why is equipment used in truly "secret" environments comprehensively
DESTROYED afterwards?

Windows already stores a lot of stuff that WE don't need.
